Commenting on the results, analysts at RBC said: "The valuation looks undemanding, at just over 6x 2017E lease-adj. EV/EBITDAR, a c.20% discount to the sector and Debenhams offers a 6.3% dividend yield. However, Debenhams has a mixed track record and we think some other UK stocks are better positioned right now and offer more upside, such as ABF (Primark international store rollout), and Marks & Spencer (becoming more competitive with lots of self-help and attractively valued)."

Real Estate Investment firms and Gas and Water utilities were also lower due to the sensitivity of their shares to yields on longer-term Gilt, which were bouncing back.
